Mannyng, Robert, or Robert De Brunne (fl. 1288-1338). -- Was a Canon of the Gilbertine Order. His work, Handlynge Sinne (c. 1300), translated with original additions from the Manuel des Péchés, a book written in French verse by William of Waddington, is practically a collection of tales and short stories on the Commandments, Seven Deadly Sins, Sacraments, etc., and is of value as giving a contemporary picture of the time. He also made (c. 1335) a translation in verse of the French Chronicle of Peter Langtoft, the second and more interesting part of which covers the period from the death of Cadwallader to the end of the reign of Edward I.
